[ATM] wedge in lenses

[Peter Abrahams <telscope@europa.com>]

After the recent discussion on wedge in lenses, and the lack of quantitative 
instructions on tolerances, I looked through many books and also found almost 
nothing.  The exception is a very dense text that I cannot comprehend, but it is 
apparently a mathematical analysis of subjects including wedge in lenses.  It is 
not only complex, but translated from Russian.
Anthony wanted a copy, so I decided to post it for others as well; however it 
can only stay up a couple of weeks.
The text is from the chapter:
L.S. Tsesnek.  Some calculations on the means of location of plane & spherical 
surfaces.
from the excellent book:
Kumanin, K.G.  Generation of optical surfaces.  London: Focal Library, 1967. 
(Translated from Russian)
There are some tiny fonts in this, so the files are bigger than they could be, 
it totals about 1.5 megs.
The subject of wedge begins a couple of pages into the scanned pages:
